In this lesson students were introduced to the concept of radians. Students were first shown shown a radian using a paper plate with the activity from NASA's Pi in the Sky unit.

Students were then asked to determine how many of their radians would fit in their paper plate circle. (If they were precise in their measurements, they should find that there are a little more than 6 in their circle. Lastly, students were then asked to ask Siri how many radians are in a circle.

Next students were given a quarter of a pizza cut at 30°, 45°, and 60° (like the first quadrant of the unit circle) and asked to determine the angle measurements in degrees and then in radians, using the information from the plate activity.

As a independent practice activity, students were instructed to make a Educreations screen capture video on a circle angle measure problem from their homework. They were encouraged to use circular object pictures from the internet to make their videos more interesting.
